Implemented query to retrieve all camera IDs, corrected removal policy on central table
Closes #19 (closed)
Functionality verified by manually creating two entries in table:
- Entry 1:
- PK: baseEntity
- SK: camera#camera_1
- Entry 2:
- PK: baseEntity
- SK: camera#camera_2
Both IDs (camera_1, camera_2) successfully returned by Lambda.
